To all whom it may concern:

Be it known that I, ALBERT J. THRownR, 'a citizen of the United States, residing at Dexter, in the county of Stoddard and State of Missouri, have invented a new and useful Cotton-Picker, of which the following is a specification.

This inventlon "relates to machines for picking cotton, one of its objects being to provide a machine which can be pulled along the rows of plants and is particularly deview which will appear as the description proceeds, the invention resides in the combinatlon and arrangement of parts and in .the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanylng drawing the preferred form of the invention has been shown.

In said drawing r Figure 1 is a vertical, longitudinal section through the machine;

Fig. 2 is a plan view thereof;

.Fig. 3 is a vertical transverse section on line 3-3, Fig. 1, the dofling wheels being shown in elevation and the toothed portions of the picking wheels being shown in section a while said wheels are in elevation;

Fig. 4 is a side elevation of a portion of one of the picking wheels, on an enlarged scale;

Fig. 5 is an enlarged section on line 5-5, Fig. 4:;

Fig. 6 is a plan view of a portion of one of the icking wheels; and V Fig. is an enlarged section on line 77, Fig. 6.

, Referrlng to the drawing by characters of reference, 1 designates an arched front axle and 2 designates a rear axle, these axles being supported by front and rear wheels 3, as

indicated. A draft tongue 4 is connected to the front axle so that the machine can be drawn readily along a row of plants.

The axles support a frame 5 and secured within this frame is a housing 6 having a forwardly-extending bottom 7 the sides of the housing being extended forwardly beyondthis bottom and shaped to constitute lifting members, as indicated at 8.

The arcuate rear wall of the housing 6 merges into the bottom 7 of said houslng and is concentric with a transverse shaft9. This shaft extends through the sides of the housing 6 and is journaled on the sides of the frame 5. The bottom of the housing is open so that plants being acted on can extend upwardly therethrough until they come into contact with the picking means hereinafter described, and an opening may also be extended upwardly in the arcuate back of the housing so as to constitute a continua- ,tion of the space in the bottom 7, this opening in the back being indicated at 6'.

Arranged on the top of the housing 6 is an 'arcuate extension 10 providedwith a front outlet 11 opening into a housing 12 which is mounted on the frame 5 and extends over a platform 13. This housing may be provided with a liftable cover 14: as shown.

Secured to the shaft 9 are spaced wheels 15 which are closed at the sides and which are also spaced from the sides of the housing 6. The rim of each wheel is faced with a metal band 16 having side flanges 17 bearing against the sides of the wheel. The rim portion 16 of the facing has annular series 'of teeth 18 struck outwardly therefrom and pointed in the direction of rotation, these teeth being preferably curved with their points extended slightly inwardly as shown particularly in Fig. 7, Additional series of teeth are struck outwardly from the flanges of the facing, as shown at 19, each tooth being substantially crescent shaped and pressed laterally from but substantially parallel with its flange, the points being extended in the same general direction as the direction of rfitation but curved slightly inwardly toward the axis of the wheel.

A standard 20 is mounted on the frame at each side of the housing 6 and supports a transverse shaft 21 extending through the housing extension 10. Secured to the transverse shaft are spool-shaped brushes 22 the flangeportions of which extend downwardly across the flanges of the facings 16 while the intermediate portion of each brush extends across and in contact with the rim portion of each wheel. The shaft 21 has a pulley 23 thereon which receives motion, through a belt 24, from another pulley 25 secured to one end of the shaft 9, the said belt 24: being twisted so that the shafts 9 and 21 will rotate in opposite directions. Another pulley 26 is secured to the other end of the shaft 9 and referred, to one of the rear wheels 3.

ceives motion, through a belt 27, from a pulley 28 secured to the rear axle 2, or, if pre- It will be apparent that when the machine is drawn forward the belt 27 will rotate shaft 9 and wheel; 15in the direction 'indicated by the arrow in Fig. 1. The plants will be received betweenthe lifting members 8 which will elevate the branches and guide r I them into the housing 6. The plants will pass throu h the space between the wheel 15, some of t e branches passing under the Wheels and others passing between the-wheels 12. A suitable receptacle can be provided in this housing for the reception of the cotton' and after the receptaclehas been filled it can be placed on a platform 29 at the back .of the machine and another receptacle placed in the housing.

What is claimed is 1. A machine for picking cotton, including a housing, means for directing plants into the housing, spaced wheels mounted for rotation in the housing and adapted to receive plants therebetween, picking teeth upon the periphery and the sides of each wheel and projecting in the direction of rota tion of the wheel, and-a revoluble; dofiing ring brush straddling each wheel and movable at a higher speed than the picking wheel.

2. A machine for picking cotton, includa housing, means for guiding plants into the housing, wheels mounted for rotation in the housing and spaced therefrom and from and extending teeth.

each other, a facing upon the rim portion of each wheel and having flanges lapping the sides of the wheel, said facing having its rim portion and flange portion provided with outstanding teeth extending in the direction of rotation, dofiing brushes straddling the upper portions of the wheels and engaging the toothed facings and flanges,

and means for rotating the wheels and brushes in opposite directions respectively,

.said. brushes being revoluble at a higher speed than the wheels.

3. A machine for picking cotton, including a housing, wheels therein and spaced therefrom, sald wheels being spaced from each other to provide a plant-receiving passage therebetween, each wheel being provided with flat sides, a facing on each Wheel having inwardly extending side flanges lapping the sides of the wheel, outstruck teeth upon the peripheral portion of the casing in the direction of rotation, the points of the teeth being slightly inturned, arcuate teeth outstruck from the flanges of the facing said teeth being eral direction as and means for and parallel therewith, extended in the same genthe direction of rotation, dofiing material from the 4. A machine for picln'ng cotton including a housing wheelswithin and spaced from the housing and spaced from each other, mealis for-rotating said wheels, a facing upon the peripheral portion of each wheel and havin side flanges lapping the sides of the whee said sides being flat and imperforate, outstruck-teeth upon the e ripheral portion of each facing and extendied in the direction of rotation, outstruck arcuate ,teeth upon the flanges of each facing and parallel therewith, said teeth being extended in the direction of rotation, spool-like brushes straddling the respective wheels and engaging the toothed surface of the facing, means for rotating the brushes oppositely to the wheels and at a higher speed, and a housing for receiving upper portions of the material dofled by the brushes from the toothed surfaces. In testimony that I claim the foregoing as my own I have hereto afiixed my signature.
